Adapting the institution of predictable breach of contract with the extended concept of obligation in the principles of jurisprudence.

The theory of foreseeable breach of contract refers to a situation in which one of the parties, despite his observations and calculations, cannot reasonably wait for the other party to execute the contract. This theory is relevant in contracts that are subject to a certain period of time. In Iran's legal system, the theory of foreseeable breach of contract is not explicitly accepted, even in certain articles, it is practically not possible to propose such a theory. But since speed and security are one of the main elements in commercial contracts, the design of this theory in Iran's legal system allows the obligor not to wait for the obligee to fulfill his contractual obligations in case of excessive delay, and by planning this type of violation, he can have a suitable time to compensate for the lost time. Although there are obstacles for proposing this theory in every legal system, its acceptance can be much more practical. In the principles of jurisprudence, in a topic entitled extended obligation, it is mentioned to perform the duty within a certain period of time, and the basics of this obligation can be used in the theory of predictable violation. The most important question that we are trying to answer in this article is with what tool the theory of foreseeable violation can be justified in Iran's legal system. By providing this goal, we have progressed from the origin of this theory to its legal analysis.
